Link building is still an important ranking factor for SEO. The quality of links is more important than the quantity, but both are still important. Linking to high-quality websites that are relevant to your website can help your website rank higher in search engine results pages (SERPs). If you're wondering if link building is good for SEO, the answer is yes - but only if done correctly. Link building can be a time-consuming and difficult task, but it's worth it if you want to improve your website's SEO.
